E-Mobility

Battery

The accumulators or batteries of electric cars and hybrid vehicles supply electric energy to the electric motor(s). This energy is then converted into the mechanical kinetic energy required for propulsion.

Battery cooling in electric vehicles

In electric and hybrid vehicles, battery cooling ensures that the lithium ion batteries are kept within an optimum temperature range.

E-Fuels

E-fuels are synthetic fuels that are produced exclusively using renewable energy. E-fuels allow CO2-neutral operation of internal combustion engines.

Electric drive

The drive used in an electric car is called an electric drive. In purely electric cars, the vehicle is powered exclusively by an electric motor. An electric motor is an electrical machine that converts electrical power into mechanical power. The way that electric motors cause electric vehicles to move is by transferring their kinetic energy to the driving axle(s).

Fuel cell

The fuel cell is an electrochemical energy converter. It is used to convert the stored chemical energy in hydrogen into electrical energy. In fuel cell vehicles, this energy is either supplied directly to an electric motor or is stored in a battery.

High voltage PTC heaters

High voltage PTC heaters are interior heating systems for electrically powered vehicles that are independent of a drive system.

Power electronics

In electric and hybrid vehicles, the power electronics control the electric drive and provide the connection between the electric motor and the high-voltage battery. They also convert the direct current (DC) for the electric motor provided by the battery into high-voltage alternating current (AC) voltage.

Thermal management for electric vehicles

Thermal management refers to the controlling of heat flows in vehicles. Thermal management is of particular importance when it comes to electric vehicles. This is because, in order to be able to operate an electric vehicle with high efficiency, it is essential to maintain the temperature of the electric motor, power electronics and the battery within an optimum temperature range. Just like with vehicles that are powered by an internal combustion engine, the heating and cooling of the interior also plays an important role. To be able to meet these extensive requirements, you need a powerful thermal management system.
